Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I've downloaded the DVD iso 4 times now, and each time the md5sum mismatches the md5sum listed on the website... and each ISO download md5sum is different. Two have been using KTorrent, one has been with Azureus, and one has been thru HTTP.
Does it usually take numerous attempts to get a good ISO? What are the risks if I attempt to burn the ISO even if the ISO does not match?
Why not download using a download manager such as kget, gwget or d4x? If you are downloading using torrents, are you using the official Suse torrent files? If so, then there is no good reason why the md5sums should be different.
I've used KGet as well with no luck. Every ISO I download is different! I read somewhere that bad memory could cause md5sum errors. Can someone provide more details on this? In the meantime, I'm going to try with a metalink. Let's see if this works.
If your PC memory is somehow damaged it can cause data stored in it to be corrupted. Thus, if you download the iso it gets corrupted in your pc ram before it is written to the disc. To determine if that's the problem use memtest (free memory testing program). Burn it on a cd and run it for let's say one night (some memories can cause errors after few hours of work, when the begin to overheat).
I had no problem downloading the iso via ftp, got the correct md5.
Several thoughts: first, it could be that you are using an unreliable mirror. Have you tried downloading from a different mirror (it's better to pick one that's geographically close to you rather than one that's distant).
That may not be necessary if you've got a valid ISO file, but if you are then having trouble burning it, the most likely causes could be that you are either burning too fast, or that you're using inferior blank disks. Burning at your drive's max speed (or close to it) increases the chance that the burn will fail. Personally, I always burn at a relatively slow speed (8X or maybe 16X) regardless of the advertised top speed of my drive. Similarly, be sure to use quality, name brand blanks. No-name "bargain" media often is a waste of money
J.W., I thought I had a good/valid ISO because I used metalinks with aria2 and when the download was completed it verified the md5sum as correct. In addition I ran md5sum again just to verify for myself: it returned a correct checksum. But the strange thing was KB3 gave the wrong md5sum checksum, but I burned it anyway ( at 2.5x ). However, the optical drive on the machine I was installing it on couldn't read it. So I ran md5sum again on the same ISO, and it was different! This really confused (annoyed might be a more accurate term) me. How can you run md5sum on the same file twice and get two different results. The only thing I can think of was that KB3 had to modify the file some how, I'm just not sure how.
killy9999 suggested I check my memory, and I did. It passed: no errors!
Anyway, so I'm going to try again, but I need to understand were the process is braking down, where can it go wrong:
1. A bad download.
2. A bad burn/write (can my Kb3 be corrupted somehow?).
3. A bad optical drive.
4. Bad media.
I will use arai2 again since it worked for me before, but this time I'm going to make a backup of the ISO before I give to Kb3, just in case. It might be tricky though deciding if it's the optical drive or the media. I'll note my findings.
ccin1492, I assume that you did continous test for over few hours? As I said some memories tend to overheat after many hours of extensive work. This can happen on Pentium IV machines sometimes (although it's very very rare). Anyway, if memory is really fine then it's really good to hear it.
K3b shouldn't alter image you are recording. This whole thing to still looks to me like some hardware problem (although I won't insist that I'm 100% right). I assume that your hd has no bad sectors, has it?
The only idea for me is that maybe you should just buy SuSE 10.2 from some computer magazine? In my coutry it cost about 10$, so it's not expensive.
